Miley Cyrus' Aussie fiancé couldn't resist showing off a new tattoo he recently got sporting a quote from President Theodore Roosevelt's famous "Citizenship in a Republic" speech—similar to one the erstwhile Hannah Montana star has.

"If he fails, at least fails while doing greatly," reads the line on the upper part of Liam's left arm, a photo of which he posted on Instagram.

In Teddy's 1910 oration, in fact, that memorable phrase actually precedes the quote Miley inked back in July on her left forearm, which reads: "So that his place shall never be with those cold and timid souls who knew neither victory nor defeat."

The 19-year-old Cyrus, who has several other tattoos including "Just Breathe" and a dream catcher on her side, got engaged to the 22-year-old Hemsworth back in May, three years after the two met while costarring together in the movie The Last Song.
